Starting A Business/How To Start?

So, I'm an experienced housekeeper for hotels and medical setting, but I just didn't make much of anything and working for someone was a pain. I want to start my own housekeeping business to kinda supplement my income because I don't make a whole lot just doing part-time at retail and my hours got super short.

What do I need? What did you do to make this happen for you? Did you bring your own supplies? Or did the customers give you theirs? Any and all advice would be lovely! I'm just trying to get some ideas and any experiences would great to hear too! I want to be successful and I hope to hear back!
